What differs between these models?
- Sustained transfer (up to MB/s): ST16000NM009G lists 249; MG09SCA16TA lists 281.
A larger cache, higher RPM or higher advertised sequential speed alone does not establish which drive is better for your workload.

Compatibility and buying checks
- A SAS drive requires a compatible SAS controller or backplane. A normal motherboard SATA port cannot operate a SAS drive.
- Check sector-format support in the controller and operating system, particularly for native 4K (4Kn) variants.
- Compare new and renewed offers separately. The manufacturer specification does not guarantee the warranty or return policy of a marketplace seller.
